The string height is fine. The supplied string set has less tension than I'm used to it, probably to the facilitate gripping for the beginner. As usual, at the beginning (about 3-4 weeks) frequent retuning required until the strings are stretched. (At Amazon, there is a set of strings for 1/2 guitars. D'Addario EJ27N-half -Saiten concert guitar set 028 '- 042' could try.)
The allocation for preschool children ages 4 to 7 years of age should better be replaced by an indication of the height, ie height approximately to 1.10 m, because there are big and small children in eienr age group. The scale length of 48 cm is in the middle between 44 cm (usually for 1/4 guitars height approximately to 1.10 m) and 53 cm (usually for 1/2 guitars Size: about 1.10 to 1 , 30 m). The neck width of 40 mm is narrow and common for guitars 1/8 - 1/4 for student guitars 42-46 mm are recommended.
The included Guitar bag is not padded, the description on this point therefore also wrong, as most given dimensions! The wrong bag is keien trifle because padded bags come at a price, the one includes in a purchase decision in eienr value with consideration.
When one attacks the Okatve at the 12th fret, then, for the braided 4th, 5th and 6th strings (E, A, D) a deviation audible. By reworking the bridge could be the probably correct, may be a different set of strings with a higher voltage behaves differently.
Conclusion: Good price for a beginner guitar to try but with weaknesses.
